If you personally are having trouble making a profitable deal, make a post and ask for suggestions.  

One thing I suggest doing as you do your research as well is to find a property on AirBnB that you like. 

This is defined as 30 days or more, and you will easily find nurses, professors, students, and more than need a 1-3 month airbnb.Speaking of, you could rent the whole space mid-term - and I suggest through airbnb or VRBO but you don't have to use those.

My suggestion would be to manage it yourself for 1-2 years, then as you acquire more rental properties, you can start using a PM. 

My only suggestion regarding Junior ADU's is to make sure you understand the law and what constitutes a "Junior" ADU.

In addition to Nathan's great recommendations, I also suggest verifying that the PMC is licensed.

I recently watched a video of a social media guru suggesting in 30 days he could have a team in place in any market in the country and be up and running with a successful real estate business.

Open to suggestion, obviously. 

I would suggest not finding a stand in.

A few things I’d suggest as a local investor:Know Your Markets: New England is a mix of urban, suburban, and rural areas with very different dynamics.
